New to the forum. Advice wanted
Hello I recently bought a 2010 Subaru Impreza hatchback Diesel online due to Covid.
Great in the snow we had, but its producing large amounts of black smoke and using too much fuel.
Not sure where to start, fuel pump, fuel injectors, EGR valve, DPF, engine flush! Have changed the air filter and added Redex.
If anyone has an knowledge of what I should do first to solve the issue it would be hugely appreciated.
Cheers
Stephen
